harbor.http.middleware.register

Register a new harbor middleware

Type:

Arguments:

• (unlabeled) (of type ('a, 'b, (('a, 'b) -> 'c)) -> 'c)

harbor.http.register

Register a HTTP handler on the harbor. The handler function receives as argument the full requested information and returns the answer sent to the client, including HTTP headers. This function registers exact path matches, i.e. "/users", "/index.hml" as well as fragment matches, i.e. "/user/:id", "/users/:id/collabs/:cid", etc. If you need more advanced matching, use harbor.http.register.regexp to match regular expressions. Paths are resolved in the order they are declared and can override default harbor paths such as metadata handlers. The handler receives the request details as a record and a response handler. Matched fragments are reported as part of the response query parameter. The response handler can be used to fill up details about the http response, which will be converted into a plain HTTP response string after the handler returns.
